[Gameplay]Thresh lantern misleading

So i wish I had been recording this, because holy damn this was the definition of Redonculous.

I was playing a match vs a Katarina and Thresh, I was playing Malphite. We all know Malphite, how large his body is, right?

So you'd think that when I was on top of Thresh lantern, I'd block it like it's supposed to as part of lantern's counterplay, right?

Wrong.

While I was just getting on top of the lantern, Katarina, from entirely outside of the lantern indicator circle, suddenly grabbed it and slid out of the base. My whole team erupted in WTFs, as they saw me not only clearly in front of her AND ON TOP OF THE LANTERN, but her outside of the lantern's shown 'grabbing range' indicator and somehow grabbing it.

Might be worth looking into, I think somewhere along the lines the circle's grabbing radius might have been increased by 50-100 units, resulting in people grabbing lantern from outside of the radius (aka: the game's clarity is compromised).

Edit: For a lil more clarity: We were inside my team's base (Red Side). Katarina had jumped in to kill some of my teammates. When she noticed she would die to my Malphite, she zhonya'd. I noticed the lantern come in during the ZHonya, immediately started walking towards lantern, giving me a sizeable headstart. Somehow just as I stood on top of the lantern and before she got in, she suddenly went from outside the lantern's circle to outside the base, drawing a mass of WTFs.
